Waterproof DS18B20 probe at Adafruit

As luck would have it, about a week or two after building the DS18B20 temperature probe from scratch since I didn’t want to wait for it to ship from China, Adafruit has added a similar probe to their product lineup. The Adafruit probe looks very similar to the Arduino-Direct one, but Adafruit is US based so shipping would be much faster and as always they provide great documentation on how to use it.
